I had the R7 Draw and i hit it realy long and did have a regular flex shaft in it but I really liked the club. I'm not sure what the price difference is, but the 425 with the four movable weights won me over I use both on the course along with original R7 Quad, R7 Super Quad, Big Bertha C4. I love the TaylorMade Drivers. But my choices in order go 425 R7, R7 draw, Super Quad, Quad, and then the BIG BERTHA. The shaft is what is real important. Get on the simulator, and ur swing speed and ball will choice a shaft for you the rest is just personal feel. The Draw was a little light and SuperQuad was a little heavy, and the 425 was what felt good to me. Find the right shaft and youll find you club alot faster. All your local retailers will all shafts in all models.
